AIR FEED FOR STOVIIES.

Application led September 7, 1921.

T 0 all whom it may concern:

Be it known that I, ARTHUR E. WHITNEY, a citizen of the United States,residing at Williamstown, in the county of Orange and State of Vermont,have invented new and useful Improvements in Air Feed for Stoves, ofwhich the following is a specification.

This invention relates to devices for feeding air to the lire pots ofcooking stoves and ranges to promote combustion, and its object is toprovide a very simple and eflicient device of this kind arranged topermit the air to become heated before it is discharged into the firepot.

The object sta-ted is attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed, and inorder that the same may be better understood, reference is had to theaccompanying drawing, wherein- Figure 1, is a plan view of the improvedstove, partly out away to disclose the interior;

Fig. 2, is a vertical section, and

Fig. 3, is a detail view in perspective.

Referring specifically to the drawing, 5 denotes the body of a cookingstove of standard design. ln Fig. 1 the top plate 6 carrying the lids isshown partly broken away to expose the parts located in the top chamber6"l through which the products of combustion pass from the fire pot 7 tothe smoke flue 8.

In the chamber 6a is located an air-feeding pipe 9 having one endpassing through the rear wall of said chamber and here provided with asuitable damper 10 for controlling the admission of air to the pipe.

The pipe 9 extends horizontally through the chamber 6 to the fire pot 7and to its outlet end is fitted a downturned nozzle having anelbow-shaped body 11.

The nozzle body 11 is positioned between the two fire bricks 13 formingthe rear lining of the lire pot 7, and the bottom of the nozzle body hasa discharge opening 12 into the fire pot. ln the inner faces of the firebricks 13 are air channels or passages 14C leading from the inner edgesof the same, near the top thereof, and opening through Serial No.499,119.

the bottom into the lire pot to provide air' outlets 15 on oppositesides of the nozzle outlet 12.

The back of the nozzle body fits snugly against the rear lire pot wall16 which is faced with the bricks 12, and this portion of the nozzlebody hasva central vertical passage or channel 17 communicating at itsupper end with the pipe 9, and leading to the outlet 19. F rom thispassage extend side branches or ducts 18 which lead to the passages 14,the latter and the ducts extending obliquely in opposite directions fromthe main passage 17.

It will be evident from the foregoing that the air passing through thepipe 9 is discharged into the fire pot 7 near the bottom thereof throughthe outlets 12 and 15, the air being delivered at three points which arespaced in the direction of the length of the fire pot. The air is heatedin its passage through the pipe 9, and as the outlet nozzle extends intothe lire pot, the air is further heated in its travel through thepassages 17 and ducts 18, and also in its travel through the passages111 in the highly heated fire bricks 13. The volume of air to besupplied is readily controlled by the damper 10 at the inlet end of thepipe 9.

I claim:

1. The combination with the hre pot of a stove and the top chamberleading therefrom; of an air feeding pipe extending through said chamberand provided with an inlet, said pipe leading to the fire pot and havinga depending nozzle thereat extending into the same and having a bottomoutlet, and a lining for the rear wall of the fire pot, said liningbeing in sections which are spaced at their adjacent ends, the nozzlebeing located between said ends, said lining sections havingair-passages opening into the fire pot, and the nozzle having airdelivery ducts opening into said passages.

2. rlhe combination with the fire pot of a stove and the top chamber'leading therefrom; of an air feeding pipe extending through said chamberand provided with an inlet, said pipe leading to the fire pot and havinga depending nozzle thereat extending into the same and having a bottomoutlet, and a lining for the rear Wall of the fire pot, said liningbeing in sections which are spaced at their adjacent ends, the nozzlebeing located between said ends, and having its rear face seatingagainst said fire pot Wall, the lining sections having air passagesARTHUR E.
